One month ago, it was 6 to 7.2
Now, BTC and PPC value has been cut by half but current market cap of NSR is 7m NBT.
Assuming that outstanding NBT quantity is still 500k NBT,
we have a reserve/liability ratio equal to : (300k + 7m)/500k ~ 14.
Of course, NSR has not a high liquidity, so we would not be able able to sell every NSR at the top price, but we can reasonably think that the ratio has increased significantly.
Good progress over 1 month on this side too.
